Seventy-seven motivations for infidelity were named by participants. The study authors grouped these by commonality to find:

1. 77% cheated because of lack of love2. 74% for variety of sexual partners3. 70% because they felt neglected4. 70% because of a situational reason (such as being drunk)5. 57% to boost their own self esteem6. 43% out of anger7. 41% because they felt little commitment to their partner8. 32% for physical sex

Furthermore, they found that men were likely to cheat for variety, sexual desire and situation while women were likely to be unfaithful because they felt neglected and ignored.
